An example of misguided advocacy. The problem here isn't that there aren't enough "can we share?" tick boxes. The problem with big data disrimination is the "big" part. Data ownership has become far too centralized within silo systems in which a few people make all the decisions. Can these people be made accountable? Not really. To start with corporations are not run democratically, but even if they were the ratio between "data subjects" and "data controllers" is such that governance won't be possible and you'd just have the "westminster village" effect.
